From the evaluation of referenced scheduling scheme provided in IEEE 802.11e standard document, we know that it does not perform well on traffic which is not strictly constant\u2010bit\u2010rate (CBR). Therefore, it is necessary to design a more flexible scheme to dynamically adjust the estimation of transmission opportunity allocated to QoS\u2010enhanced stations with different characteristics of applications. This paper aims to present a data rate estimation algorithm for the scheduler of the IEEE 802.11e hybrid coordination function controlled channel access.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Design\/methodology\/approach<\/jats:title><jats:p>The performance of the algorithm is evaluated through Network Simulator \u20102.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Findings<\/jats:title><jats:p>With the proposed algorithm, the QoS access point can provide guaranteed parameters such as delay and throughput for both the real\u2010time variable\u2010bit\u2010rate and CBR traffics.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/valve<\/jats:title><jats:p>The paper presents a data rate estimation algorithm for IEEE 802\u201011e HCCA scheduler.<\/jats:p><\/jats:sec>","DOI":"10.1108\/17427370710856219","type":"journal-article","created":{"date-parts":[[2008,2,16]],"date-time":"2008-02-16T07:03:32Z","timestamp":1203145412000},"page":"243-256","source":"Crossref","is-referenced-by-count":3,"title":["Data rate estimation algorithm for IEEE 802.11e HCCA scheduler"],"prefix":"10.1108","volume":"3","author":[{"given":"Jing\u2010Rong","family":"Hsieh","sequence":"first","affiliation":[]},{"given":"Tsern\u2010Huei","family":"Lee","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022020320344861200_b1","unstructured":"Ansel, P., Ni, Q. and Turletti, T.
